Current induced in a coil from inside

[Northprairieman]

Hi there,

If you have a stream of protons passing through the inside of a coil of wire (coils of wire at 45 degrees to current of protons) and say the current of protons induced a certain current in one of the loops, would the current induced in one loop be equal to the current in the entire coil? Or would you times the current induced in one loop by the number of coils to get the total current induced in the coil?

So does your current create a change in magnetic flux .

Yes, the inner current creates a change in magnetic flux in the loops. I have already calculated that. I found the current that should be created in one loop, I was just wondering if you could multiply that by the number of loops to get the total current induced in the coil, or whether the total current induced in the coil is just equal to the current induced in one loop.

The current in the coil is equal to the current in a single loop. It's the voltage across the loops that will add.

If you short out the coil or use a superconducting coil, then LESS current will go through the coil if there are more loops, because the amount of current will be just big enough to counteract the change in magnetic field from the protons, and you don't need less current to produce the same magnetic field.
